netrc: .netrc - login information for ftp, rexec, and rexec()DESCRIPTION
The file contains login and initialization information used by the
autologin process, by the library routine, and by the command (see
ftp(1), rexec(3N), and remsh(1)), respectively. This file is optional.
It exists, if at all, in the user's home directory.
If the file contains password or account information for use other than
for anonymous its owner must match the effective user ID of the current
process. Its read, write, and execute mode bits for group and other
must all be zero, and it must be readable by its owner. Otherwise, the
file is ignored.
The file can contain the following tokens, separated by whitespace
(spaces, tabs, or newlines) or commas To include a comma as part of a
token, enclose that token in quotation marks ().
Identify a remote machine name.
The autologin process searches the file for a token
that matches the remote machine specified on the
command line, as an command argument, or as the
parameter of Once a match is made, the subsequent
tokens are processed, stopping when the end-of-file
is reached or another token or a token is encoun‐
tered.
If the remote machine name has an alias host name,
and both the official host name and the alias are
present in the file, the client gives precedence to
the official host name over the alias when search‐
ing the file. If an alias is given as an entry to
the command, and in the search from the top of the
file to the bottom, the client finds the alias host
name before it finds the official host name, it
will use the alias's entry. However, if it finds
the official host name first, it will use the offi‐
cial entry even though the alias host name also
exists in the file. So the high precedence given
to the official host name requires placing the
official host name entry last in the file for when
aliases exist.
Same as except that matches any name. There can be only
one token, and it must be after all tokens. This
is normally used for as follows:
This provides automatic anonymous login to machines
not specified in This can be overridden in by using
the flag to disable autologin.
Identify a user on the remote machine.
If this token is present, the or autologin process
initiates a login using the specified name. If
this token matches the user name used by the com‐
mand option, or, by default, the local user name,
uses the token, if present.
Supply a password. If this token is present, the autologin process
supplies the specified string, if the remote server
requires a password as part of the login process.
Note that if this token is present in the file for
any user other than aborts the autologin process if
the is readable by anyone other than the owner.
Also note that the passwords in are not encrypted.
Supply an additional account password for
login. If this token is present, the autologin
process supplies the specified string if the remote
server requires an additional account password, or
the autologin process initiates an command if it
does not.
Define an macro. This token is just like the command. A
macro is defined with the specified name; its con‐
tents begin with the next line and continue until
an empty line (consecutive newline characters) is
encountered. If a macro named is defined, it is
automatically executed as the last step in the
autologin process.
EXAMPLES
The following is a valid entry for the host whose account has the pass‐
word
WARNINGS
It is a security risk to have unencrypted passwords in a file.
